Abstract

PROJETOR DE LUZ E SISTEMA DE VISÃO Um projetor de luz compreende uma pilha de elementos óticos planos em camadas, em que a pilha compreende um grupo (103) e elementos óticos planos (107-111) dispostos para fornecer uma série de padrões de luz. A pilha pode compreender especificamente um grupo de camadas transparentes que possuem padrões opacos de tal forma que a luz que se propaga através das camadas resulte nos padrões de luz. Os padrões de luz atingem um conjunto de microlentes (101) que é disposto para fazer foco dos padrões de luz em diferentes distâncias focais. Em alguns cenários, podem ser utilizados elementos óticos programáveis para gerar os padrões de luz. Um sistema de visão pode determinar características de objetos com base em reflexos dos padrões de luz projetados. A abordagem pode fornecer particularmente um projetor de luz eficiente, mas de baixo custo.
